Brett beat me to it.
Yes a new version is up and it has several changes.
I have added an operation for User Entered Gcode. This will let you insert any gcode, anywhere in the program between operations. This might be useful to enter comments to document setups, or material or whatever you need. Any Gcode you enter will be displayed in the toolpath if it generates moves.
I added an operation called Tool Strategy. There are times when you want to change tool parameters, but not make a tool change- like changing feed rate, or spindle RPM, or ramp angle.
Brian changed the circle cut routine to generate spirals instead of the previous zig-zag cut. Now the tool will just keep making circles, ramping down over whatever arc length is needed to meet the ramp spec.
I changed the rectangle routine to do helical ramps down to step depth, then an arc lead-in and arc lead-out. It now has a groove option that uses teh zig-zag ramp into the work, but cuts only a grove.
Brian fixed a bug in the toolpath screen that didnt handle metric G73 correctly. This one in some systems could cause a crash.
A few other clean up kind of fixes were made.
Any feedback will be appreciated.
